  • How to find the display resolution corresponding to the motherboard CPU

    Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

  • Advantages and disadvantages of SPI interface and QSPI interface for small-size LCD screen

    In short, for small-sized LCD screens, QSPI is a better choice: through pin multiplexing and queue mechanism, while maintaining sufficient transmission rate, PCB design and master control resource usage are greatly simplified, which is especially suitable for scenarios that require dynamic display and limited space. SPI is only applicable to extreme cases where the driver IC does not support QSPI or has extremely simple functions. When actually selecting, it is necessary to first confirm the interface specifications of the screen driver IC (some screens support both SPI and QSPI, which can be switched by configuring pins).

  • 5 inch sunlight-readable display, semi-reflective and semi-transparent, low power consumption

    Conventional 5 inch display screens cannot be seen clearly under strong outdoor sunlight unless they have a brightness of 2000 lumens. To achieve this brightness, the number of high-brightness LED lights needs to be increased, which will increase power consumption and reduce battery life. Our company has successfully mass-produced a semi-transparent and semi-reflective 5 inch screen with a resolution of 800*480 and an RGB interface. It can display clearly in the sun without turning on the LED light, which reduces the power consumption of the machine and is the first choice for many outdoor electronic devices.

  • How to prevent the LCD screen backlight from turning yellow

    To avoid the problem of yellowing of the backlight material of the TFT LCD screen, it is necessary to start from many aspects such as material characteristics, usage environment, and driving method. In particular, it is necessary to pay attention to the selection and maintenance of the core components of the backlight module (such as LED lamp beads, light guide plates, diffusion films, etc.).
